Theit astener,unit A .has anne-'piece metalcas'ing partor lfastenercarryingv and f attaching part 3y and a one-pieee .studmem-:fi .bers 4. f v'The fastener--zcarrying andA attach? ing part has a flange portion 5 provided with; v Y y a continuous outerperipheral portion,-The i' {'angev fportion 5 Ivsurroundsanj apertureqk1 6 *Y through which the head 7 and neck 8 ef'thegl stud pass .f From ytheinn'erfedge'of theiiange Wardly toy provide a'y Walll 9 l'perpendifeular to .10 parallel With the 'axis/of theunit. At thev i; p 4; i A* free edge of th'ewalllflO I, have provideda number of attaching prongsjll. 'Between' thefff" prongsnll I; have' provided inwardly:@-b'enty 'vears12 (Fig-2) whicharefparallelwiththe A kWal119. The-ears 11 are spaced `from thefwall ,.9180 that, .the'base '12. Ofithe ,Stud he' aS- sembled between the ,ealsy/lilfand: wall;-

@fram-these y' best shown in Fig. 1. The diameter of the base 12 of the stud is less than the diameter of the space enclosed by Lhe wall 10 so that the stud may shift to a limited extent in any lateral direction relative to the carrying and attaching part.

The fastener unit A is attached to the upholstered backing 2 by inserting the unit into a hole 13, previously formed therein, until the flange portion 5 rests against one face of the backing. Then the attaching prongs 11 are bent outwardlyand downwardly against the oppositeA face'of the backing (Fig. 2) so that the base of the stud and substantially all of the stud carrying and. attaching part are.

confined between the two faces of the backing, as best shown in Fig. 1. y

Referring now to Figs. 4 through 6 I have shown an installation which Vist substantially the same as that shown in Figs. 1 and 2.Y In this installation the stud' holding andi attach ing part is of'slight'ly' different construction. Therefore, I shall designate the fastener unit shown in Figs. 4 throughv 6' asthestudE uni'tlB..

'Ish'e studl carrying and' attaching partV of the unit B is pressed from a single piece of sheet metal= which; in its blank form is in the shape of a disc. The disc is cut tov provide a number' of sets of" ears or petals (Figs. 5 a-nd 6) which are for different purposes. These petals are located at the in-ner edge of a ring-like portion 14 Vand three of; them marked 15 rem-ain inthe same plane as. the ring-like portion. Three otherears or petals marked 16. are bent; at right angles to the ring-like portion 14 andI these extend inwardly in-` spaced' paralleli relation to the petals 15j. These petals I5v and 126E forin means for".cooperation witlii the base of'thestud to holdl the stud: in laterally shiftable assembled relation with the-stud carrying and attaching part.

' i The remainingtli'ree petalsmarked?l eX- L 118 with; ai wall'portion 19. at itsinnerperiphery and. an inwardly extending wall 20.- at the other endk of the wall 118, asshown in Figs. 7 and; 9.. I? have= also provided` aa number.- o'tea'ns 2.1i cutV from the flange portion-18 and bentinwandly'inspacedparallel relation with-the wall 2.02 rThus the'ears 21' and; wall 20 provide the. means for holding thev base ofiA thestud in laterally sliiftable relation. prongs-22 extend from the inner edge of'tlie wallik 20- at right angles thereto andi lare adapted tocooperate with the flange V18 to secure the stud unit C to a support.

It should be noted that in each of the stud units above described the stud carrying and attaching part has an annular ange which extends outwardly beyond the remainder of the Vpart and has a 4continuous peripheral edge. This flange serves as a part of the attaching means and at the same time provides satisfactory means for permitting feeding of the units in an automatic attaching machine. rIhe units are; also simple, durable and inexpensive and therefore are very desirable articles of manufacture.

While I have illustrated and described several embodiments of my invention, I do not wish to be limited thereby as the scope of my invention is best defined in the following claims.

Claims:

1. A fastener unit comprising,- in combination, a casing' part and a snap fastener element, mea-nsengaging said snap fastener element and holding it in assembled relation with said casing part, a` continuous flange portion extending lateral-'ly outwardly beyond the means engaging the` snap fastener element and attaching mea-ns formed integral withthe casing part and adapted to cooperate with said flange to secure the fastener unit to a support.

2. A fastener unit comprising; in combination, a stud holding and attaching part and a fastener stud secured thereto, said stud having ahead, a neck and a base and said stud holding/part havingmeans engaging the base yofthel stud to hold the stud in assembly with beyond the means engaging the studbase and a numberof attaching prongs extending parallelfwit'h the axisofthe stud and adapted to be bent outwardly to cooperate with saidcontinuous flange and secure the fastener unit to a support.
